WEBSTER GROVES, MISSOURI TRAVELING- LOADING- DEVICE' 7 Application filed. July 21, 1932. Serial No. 623,704.

This invention relates to traveling loading devices, and with regard to certain more specific features, to traveling loading devices adapted particularly for the loadlng of carbonizing vertical coking retorts with briquettes or like Shaped objects.

Among theseveral objects of the invention may be noted the provision of a traveling loading device of the class described wh1ch 10 is adapted to receive uncarbonized briquettes, as from hopper, and place them in the interior of a coking retort, in such manner that the briquettes are not subjected to great falls or disruptive forces at any time; the

provision of a device of the class described which is adapted for ready installation in connection with an entire bench of'coking' retorts, and which may be used with equal facility for any] retort in the bench; the provision of a device of the class described which includes telescoping means whereby, at the time the charge is delivered to the retort, the device extends substantiallyto the bottom of the retort; and the provision of a device of the class described which is relatively simple in construction and operation. Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly comprisesthe 3 elements and combinations of elements, features of construction, and arrangements of parts which will be exemplified in the struc tures hereinafter described, and the scope of the application of which will be indicated in the following claims. I In the accompanying drawings, in which is illustrated one of various possible embodiments of the invention, V Fig. 1 is a side elevation of a crane embodying the present invention, the charging means being shown in tilted position ready to receive a charge;

Fig. 2 is a side elevation similar to the crane of Fig. 1 with the charging means in vertical position ready to be lowered into a retort; Fig. 3 is a side elevation similar to Fig. 2, partly in section, showing the charging h means in lowered, extendedposition in the interior of a retort; and,

their falling from the top to the bottom of the vertical .retort. as the retort is filled.

Such raw briquettes cannot in general be safely dropped more than a few feet at the most. The present invention provides a charging means whereby vertical cokingfretorts of the class described may be satisfactorily utilized for the carbonization of briquettes, in that it provides means whereby the retorts are filled with briquettes without at anytime necessitating any particul'arly long fall for such raw. briquettes.

Referring now more particularly to Fig.

1, numeral 1 indicate's'a b ogie wagon which runs on wheels 3 on tracks 5 provided on top of the retort'bench 7. Numerals 9 indicate, diagrammatically, the individual retorts of the bench. The bogie wagon 1 comprises a suitable rectangular frame work of steel beams or the like, having asuperstructure comprising sloping uprights 11 and top pieces 13 on each side thereof. The superstructure is desirablyreenforced by bracing beams 15 (see'Fig. 4:), and horizontal beams 17. All i of the beams 11 13, 15 and 17 desirably con-' stitute steel channel beams or the like.

' fAt one end of the bogie wagon 1 is provided a driving motor 19, whichby means of a suitable transmission drives the wheels 3 to run the wagon as a whole along the top of the retort bench. The motor l 9 also drives a drum 21, which is utilized as hereinafter described. I e

Numeral 23 mdlcates a charging means or loading basket comprising a top funnel or hopper portion and a lower extending portion 27. The extended portion 27 comprises telescoping members or sections 29 and 31 (see also Fig. 3), the portion 29 telescoping exteriorly of and surrounding the portion 31. The portion 31 is permanently afiixed to the hopper portion '25, while the portion29 slides upon the'portion 31.

A reenforcing band 33 is provided around the upper end of the portion 29, and extend ing from each side of the band 33 is a trunnion 35. The trunnions 35 are held in a sliding block 37, which has a slot 39 therein in which the trunnions 35 may slide," The block 37 in turn slides in open-ended tracks 41 mounted'on the superstructure of the bogie wagon.

Attached to thetop of the sliding block g 37 is a wire cable 43, which passesupwardly over an idler pulley 45 and thence tothe drum 21 driven by the motor 19. As will be disclosed more fully hereinafter, the wire cable 43 comprises the means for letting the charging device down into the interior of the retort, as it is paid out from the drum 21.

The lower .end of the outermost telescoping portion 29 is provided with a pair of hinged doors which swing together completely to close'the bottom of said portion 29. Pivotal- 1y secured to the inner, swinging edge of each.

door 47, at each end of the portion 29, are

links 49, which are pivoted at their other ends,

respectively, to blocks 51, which slide in suitable guides mounted on a band 57 surrounding thesection29. The blocks 51 have an outward projection 53 thereon, which serves for latching purposes as will be described hereinafter. From the top'of the block 51 a 40 link or cable 55 extends to the bottom of the sliding block 37.

A second reenforcing band 57 is provided near the bottom of the telescoping portion 29 in the region of the block 51. On the band 57 are mounted a pair of pawls'59, which are pivoted in such manner that, with the device asin the Fig. '1 position, they do not interfere with the action of the block 51, but when said block 51 is lowered, the pawls 59 rotate and look around the projection 53. The pur pose of this arrangement will be apparent in the description ofthe operation hereinafter. V I

A third reenforcing band 61isprovided at the telescoping portion29 between the bands 33 and'57. v r

Mounted on the bogie wagon 1, at each side thereof (see Fig. 4) is a pair of pawls 63,

which are rotatably pivoted on bolts 65. With 1 the pawls 63 upstanding, as illustrated in Fig. 4, they do not interfere in any manner with the movement of the charging means, but when said pawls are swung inwardly on their pivots, they are in position to engage H the reenforcing band 61 to prevent lowering of the charging'means' into a retort. This arrangement may be utilized when it is de- 'Fig. 1) are a pair of stops 67, which are spaced apart a suiiicient distance to engage the'pawls 59 on movement of the telescoping portion 29 in an upward direction, but to clear said pawls 59 on downward movement of the telescoping portion 29, for purposes to be described.

Sidewardly mounted upon the superstructure of the bogie wagon is a transverse shaft 69 ,which is supported in bearings 71, and

which is provided with a series of drums 73 thereon. Afiixed to the drums 73 are chains 75,:which are provided at their ends with hooks .or rings 77 adapted to engage eyes 79 mounted in the side of the hopper portion 25.

The shaft 69 is also provided with a hand.

wheel 81 and'a ratchetwheel 83 and pawl 85 for maintaining the hopper portion 25 in any desired'angular position.

The operation of the device is substantially as follows? The initial position of the charging'device is, for' example, that shown in Fig. 2, where the telescoping portions'29 and 31 are collapsed and vertical, and the discharge doors 47 are closed. The first step in filling the retort comprises driving the bogie wagon to a position under a charging hopper 87 indicated diagrammatically in Fig. 1, where it is to be filled with the raw briquettes. Having arrived in such'p'osition, the entire charging means is now tilted on. the trunnions 35 by. suitably manipulating the hand wheel 81 to run up the chains 75 on the drums 7 As this is done, the entire hopper and telescoping portion'assembly comes into the sloping position shown in Fig. 1, relative to its vertical axis. In this position the raw briquettes are allowed to runfroin the hopper 37 into the hopper portion'25, the general slant of the whole device eliminating the necessity for the raw briquettes to fall freely for any distance whatsoever.

It will'be appreciated that the entire weight of the charging'means is supported, through the trunnions 35, by the wire cables 43.

"lVhen the telescoped portions 29 and 31 ing into a'retort to discharge its load 01.

raw briquettes. -The loading of too many briquettes into the hopper portion 25 is preferably avoided, as this would shift the center ofgravity of the charged loading means into the hopper portion 25 and prevent righting of the charged loading meanswhen the chain 7 5 is paid out.

a The bogie wagon is run to the retort desired to be filled, at which time the motor 19 and drum 21 are' manipulated sothat the cable 43 is slowly paid out. Under these circumstances, the entire charging means is first gradually lowered toward the mouth of the selected retort 9, the sliding block 37 meanwhile passing out of its tracks 41. As the telescoped portions 29 and 31 sink into the retort, projecting stop bars 89 (see Figs. 3) on the hopper portion 25 abut suitably positioned stop bars 91 mountedon the platform of the bogie wagon. This prevents further lowering of the hopper portion 25 of the charging device 23. 7

As the cable 43 is further paid out, the next thing that happens is that the section 29 extends telescopingly away from the section 31, and continues so to do until a top flange 93 on the portion 29 abuts a bottom flange 95 on the portion 31, in such manner that further extension is prevented. In this downward motion, the pawls 59, being in the retracted position, clear the stops 6?. While the extension has been taking place, the briquettes flow without any falling, from the hopper portion 25into the upper telescoping portion 31, and when the telescoping portions 29 and 31 are fully extended, substantially no briquettes remain in the hopper portion 25.

As the cable 43 is still further paid out, the weight of the briquettes upon the doors 4:? presses said doors open and by this time the bottom of the portion 29 has reached almost to the bottom of the retort, and as the doors 47 open, the briquettes experiencebuta very short fall before they are definitely stopped by the bottom of the retort. Finally, the cables 43 are paid out to such an extent that the projection 53 of the block 51 becomes locked between the pawls 59. Efi'ectually, this means that the doors 47 are locked open.

The direction of rotation of the drum 21 is now reversed, and the cables 43 rewound thereon. The upwardly moving cable cannot reclose the doors 47 because of the engagement of the pawls 59 and the projection 53, but it does slowly pull the entire lower section 29 again into retracted, telescoped position upon the section 31, meanwhile delivering the charge of raw briquettes into the re tort. All of this delivering of briquettes goes on without said briquettes falling through any appreciable distance, and thus their breaking is avoided.

After the sections 29 and 31 have completely telescoped, further pulling on the cable 43 lifts the entire charging means 23 back up out of the retort, and slowly returns said charging means to its Fig. 2 position. As the pawls 59 pass the projections 67, their sidewardly extending portions, being'now in retort, for coking.

extended position, are engaged and rotated downwardly, thus opening the claw portions and releasing the projection 53. Thereupon the piece 51 moves upwardly relative to the section 29, and, by means of the links 49,

doors 47 are closed, and the device again becomes supported solely by the trunnions 35 resting'in the ends of the slots 39 in the blocks 37. The device is now ready for reloading and charging another retort.

' One or more stops 97 is desirably provided onthe upright beams 11 in order to bear part;

of the weight of. the charging means 23 when in its sloping, Fig- 1 position.

As indicated in .F ig. :41, the bogie wagon 1 may be sutficiently wide to accommodate several charging means 23, as for aretort bench in which several retorts are located one behind, another. Or, the bogie wagon may carry but one such chargingdevice 23.

From theabove it will be seen that the invention provides ameans whereby the raw briquettes may be carefully handled, without any substantial'fall, from the bins in which they are accumulated after briquetting up until the time they are deposited in the In view of the above, it will be seen that the several objects of the invention are achieved andother advantageous results at-" tained. a 7
